did the fix require a reset to the data on your watch, did you have to re-add your credit cards? my update says it may require a reset of data (non-lte s3 frontier)
On mine it had that stupid "stay connected to your phone" warning before and after the update it wasn't there anymore. as of right now it is working fine without any reset.
I also remember a Samsung Pay update recently... maybe that is what fixed it?
